- TUNNEL NINEPIN GAME.

SPECIFICATION forming part of Letters Patent No. 671,172, dated April 2, 1901. Application filed September 7, 1900. Serial No. 29,314. (No model.)

To all whom it nuty concern.-

Be it known that I, WOLF SENZER, mechanic, a citizen of- Austria, residing at Vienna, Province of Lower Austria, Austria- Hungary, have invented certain new and useful Improvements in Tunnel Ninepin Games; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it a'ppertains to make and use the same.

This invention relates to a tunnel ninepin game, and may be as well applied to a tenpin game. i An essential feature of this invention is that the pin-board is provided with a tunnel having a screw-shaped bottom which surrounds the position of the pins completely. The ball which is to throw down the pins is led toward the same through this tunnel, whose outer walls are arc-shaped near the mouth for the purpose of deviating the ball to the one side or the other. There is further provided a plate-spring which, in combination with other parts, forms a feature of my invention.

Another feature of this invention is that the pin-board is surrounded by a groove in the ground-plate for the purpose of stopping the ball when it has passed the position of the pins, preventing in this manner the rebounding of the ball.

The invention is represented inthe accompanying drawings in Figure 1 in plan view, and in Fig. 2 in front view. Fig. 3 is a section through Fig. 1 on line at x.

The pin-board Z), marked for the position of the pins, is provided on the ground-plate a and surrounded by a wall e, forming a closed tunnel g, with screw-shaped bottom. The opening h, into which the balls are to be thrown, is arranged on the highest point of the tunnel, while the mouth f, through which the ball rolls out, is situated in the plane of- 5 the ground-plate.

nel is curved and the latter closed with this curved portion, forming in this manner a guide-plate for the ball, so that the latter is other toward the pins, proportionably to the inertia with which it arrives at the end of the tunnel. For the purpose of assuring this deviation and to increase the deviating efiect of the plate m there is provided a spring is,

against which the ball bounds before coming out of the tunnel, whereby it is deviated by the elasticity of the spring 70.

The mouthf of the tunnel may be provided with guide-plates z' i, which prevent the ball from rolling sidewise.

Surrounding the pin-board in the groundplate there is a groove 0, with an interruption at a point opposite the mouth f, so as to allow the balls to roll toward the pins. This groove has the further purpose of stopping the ball when it has passed the pin-board and to prevent the rebounding and facilitate the taking out of the ball.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. A ninepin game composed of a groundplate a, a pin-board I) provided thereon, a groove 0 adjoining the pin-board and interrupted in the front, a wall 6 surrounding the ground-plate and forming a tunnel g having a screw-shaped bottom and curved in the front whereby the tunnel is closed, an opening h through which the ball enters and arranged on the highest point of the tunnel g. and the mouth f through which the ball rolls out, and situated in the plane of the groundplate, as specified.

2. A ninepin game composed of a groundplate a, a pinboard 12 provided thereon, a groove 0 adjoining the pin-board and interrupted in the front, a wall 6 surrounding the ground-plate and forming a tunnel 9 having a screw-shaped bottom and curved in the front whereby the tunnel is closed, an opening 7t through which the ball enters and arranged on the highest point of thetunnel g and the mouth f through which the ball rolls out, and situated in the plane of the ground- 5 plate, and guide-platest' '0' provided on the mouth f, as specified.

3. A ninepin game composed of a groundplate a, a pin-board I) provided thereon, a

more or less deviated in one direction or the i groove 0 adjoining the pin-board and inter- 10o mouth f, and the plate m provided with the ro spring k, as specified,

In testimony that I claim the foregoing as my invention I have signed my name in presenee of two subscribing Witnesses.

WOLF SENZER.
